Based upon the theory that the lateral column was the most important in assessing ankle stability, the Danis-Weber classification was devised to describe ankle fractures in relation to the distal fibula.

Two different but complementary classifications are employed in assessing these injuries. The Lauge–Hansen classification is based on the adduced mechanism of injury, which is useful in planning how to reduce the displaced fragments by reversing the injurious forces during manipulation of the ankle. The Danis–Weber classification focuses on the level of the fibular fracture: fractures distal to the tibiofibular joint generally leave the syndesmosis intact, whereas indirect fractures above that level must necessarily have damaged the syndesmotic ligaments. If the mortise becomes unstable, the talus can be displaced. Thus, careful interpretation of the x-rays is important for both diagnosis and treatment.

Figure 3.13 Danis-Weber classification of ankle fractures. There are three types depending on the level of the fracture of the fibula (a) Type A: below the syndesmosis (b) Type B: at the level of the syndesmosis (c) Type C: above the syndesmosis (reproduced with kind permission from Solomon L, Warwick DJ, Nayagam S.

The source population was dominated by a Caucasian population. We excluded only examinations with open physes and believe that our results generalize well in a regular clinical setting, though we would expect more negative cases and simple fractures than in our material. The clinical performance of the algorithm may therefore differ from the sample performance. Our results also extend to the Danis–Weber classification to the extent that it is a subset of the AO classification.
